SPECIFICATION forming part of Letters Patent No. 746,519, dated December 8, 1903.

Application iiletl October Z8, 1903. Serial No. 178.830. (No model.)

To a/ZZ whom t may concern.:

Be it known that I, SINCLAIR J. JOHNSON, a citizen of the United States, residing in Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvementsin Dumping-Cars, of which the following is a specification. y

This invention pertains, to doors and dooroperating mechanism for dumping-cars, and in its present formsuch doors and door-operating mechanism are designed for use in con. nection with such cars as deliver' from the side.

An object of this inventionV is to provide doors and operating mechanism therefor, whereby such doors may be operated simultaneously and from a given point, preferably through the instrumentality of a single oscillating shaft, whichtnay be suitably disposed, and to also provide an absolute lock for the doors when closed.

Other objects will become apparent the following specification.

In such drawings as accompany this speci- [ication for the purpose of rendering the description more intelligible, Figure lis an elevational View of a dumping-car provided with the improved doors and operating mechanism therefor. Fig. 2 illustrates a transverse section on linea/:oc of Fig. l and show operating from mechanism and doorsboth in their open and closed positions. Fig. 3 illustrates one form of connection employed in the train of mechanism, the same being illustrated in one position. Fig. 4 is a similar view illustrating the same in another position. Fig. 5 is a modified form of construction. trates one form of crank mechanism used in conjunction with the operating mechanism. Fig. 7 shows a modified form thereof, and Fig. 8 illustrates an embodiment of the invention wherein each door may be operated independent of the other and from dierent points. t

Similar characters of reference indicate like parts throughout the figures.

Shown for convenience of illustration is a car l of anyordinary type and of any suitable construction and which preferably may be provided with the usual inclined bottom 2, which may lead to central portions of the bottom of the car, from which portions ,may extend laterally and downwardly a plurality Fig. 6 illusof side deliveries 3. In such present form of construction, as shown, the openings 4.0i the deliveries may bedisposed angularlywith relation to the perpendicular axis of the car; but while this form of construction may be contemplated in practice such construction may be varied at will. As closures for the opening 4 there may be provided a plurality of doors, such as 5, which may be suitably mounted to swing against said openings and also therefrom at will, and in the present instance such mounting may be accomplished, as shown,v by pivoting the doors to the bodyV of the car, as at 6, in any suitable manner, and the doors proper may be attached to said body, as herein shown, by brackets 7 or may be attached in any other suitable manner. This point is placed above the plane of the door and in such a position that the door when open will not swing out too far beyond the l.side of the car and at the same time will not allow the door to swing down too far toward the track. The point from which the doors may behung can be changed at will to regulate the swinging of the doors, whereby to permit their proper operation in connection with the door-openings. In such a door construction the load is supported more by the hinge-pivot and not so much by the operating mechanism, as is the case with doors which are hinged at one edge and in or below the plane of the door, and can therefore be more readily operated and controlled,.so as to allow the doors to be stopped at will at any point. y Beneath the car l maybe located a shaft 8, which may be disposed substantially centrally parallel to the longitudinal axis of the car and which maybe carried in bearings 9, which maybe borne by struts 10, and substantially midway of this shaft or at any point where it is desired to connect on that portion of the dooroperating mechanism which is connected to the doors the shaft 8 maybe suitably bent, as at 1l and 12, as shown, or otherwise snitably displaced, whereby to permit certain parts of the mechanism to pass beyond the central axis of the shaft 8.

From either side of the shaft 8, and preferably at those portions `which are displaced, may proceed laterally-extended members or crank-arms 13 and 14:, at or near the ends of each of Which maybe pivots 1-5 and 16,Whereon to mount shafts or rods 17 and 18. These rods may be pivotally connected to the doors 5, as at 19 and 20. Turnbuckles 21 and 22, as seen, for instance, in Figs. 2 and 8, may be employed, or any equivalent devices for adjusting the length of these rods 17 and 18, so that the respective doors 5 may properly close the openings. When the doors are in a closed position, as seen, for instance, in Figs. 1 and 8, it will be observed that the shaft 8 has been rotated, so that the pivot-points of the crankarms 13 and 14 have passed to a position beyond the line running through the center of the pivots 19 and 2O and the center of the shaft 8, thus is secured an automatic locking function, for when the aforesaid pivot-point is beyond the aforesaid` line the tendency is to rotate farther and not backward, and as it cannot rotate farther on account of a stop 23, suitably provided, the doors are securely locked. However, if desired, a drop-pawl 24 may be provided to prevent any rotation of the aforesaid shaft beyond a predetermined point. It will also be seen that in order that the pivot-pointson the cranks can pass beyond the aforesaid lines of centers the shaft 8 may be bent, as Seen in Fig. 6, or otherwise offset, or else the rods, as shown in Fig. 7, may be suitably bent. At any point in the length of this shaft 8 may be suitably coupled a second shaft 25, which may extend to or beyond the end of the car 1, from which point the shaft 8 and the shaft 25 may be operated, and

for this purpose any suitable device may be.

located on the end of the shaft 25. This device in the present instance preferably cornprises a Wheel or arms with studs projecting therefrom, and a paWl 24, as shown, is provided to act in conjunction with said studs to hold the wheel or arm in any position at Will. At or near the opposite end of the shaft 25 is formed an offset 26, from which proceeds a portion 27, provided with a slot 28, Whichis adapted to take over a member 29, which may be in the form of a stud proceeding from the shaft 8, and this shaft 25 is held to the member 29 by suitable means, such as a pin 30. By means of such connection the rotation or oscillation of the shaft 8 by a similar movement of the shaft 25 is conveniently effected, whereby to operate those portions of the train of mechanism which are directly connected to the main shaft 8 and the various doors for the openings. When the doors are thrown open, as seen in Fig. 2 in dotted lines, or in Fig. 8, and the position of the parts as shown inFigs. 6 and 7 are reversed, a set of stops or rests 31 and 32 are adapted to bear against the ends or pivot-bearings 15 and 16 of the crank-arms 13 and 14, and the rotation of the shaft 8 is thus automatically stopped when the door is fully opened.

In such form as is thus far described it will be observed that froma main shaft, preferably located substantially midway the width of the car and beneath the same, a plurality of doors for the openings which are located to deliver from the side may be operated and that such operation may be accomplished simultaneously both in closing and opening the doors, and, further, that when the doors are closed there is provided a stop or rest adapted to act upon the crank-arms of the mechanism for operating the doors, which stop or rest is so located or disposed as to be predeterminedly effective for positively maintaining the absolute contact of the doors against the openings.

While in practice it may be preferred to employ the form of mechanism hereinbefore described-that is, a single shaft centrally disposed for operating the plurality of doors simultaneously-it may also be desirable at Will to employ a modified form-such, for instance, as shown in Fig. 8, wherein theruse of an individual shaft for each door or each set of doors for the openings at one side of the car and another individual shaft for the doors for the openings at the other side is adopted. Especially will this be desirable in dumping the contents of a car from one side. For this purpose the arrangement of the openings 4, the doors 5, and the method of swinging said doors may, if found convenient, be the same or similar to that Which has been herein before described in connection with the single-shaft arrangement. The doors and the connection between said doors and the shaft may be the same or similar, and, as shown, comprises laterally-disposed members 33 and 34, respectively, each of Which may be. connected to individual shafts 35 and 36, respectively, which may be disposed on the side of the central portion of the car, preferably in bearings 27 and 28, which may besupported or carried by struts 39 and 40. Similar arrangements may be adopted for connecting these laterally-disposed members 33 and 34 With the doors 5, as has been before explained-that is to say, the connection may comprise rods 17 and 18.

It will be noted that when the shafts 35 and 36 are partially rotated the members 33 and 34 Will operate in a manner similar to that hereinabove set forth and will likewise open andclose the doors.

If desired, a substitute form of connection between the shafts 8 and 25-for instance, as shown in Figs. 3 and 4- may be employed, and, among others, that form Which is shown in Fig. 5, which consists of a gear construction, may be used. In this arrangement a pinion 41 may be provided on the end of the shaft 25 and another pinion 42 on the shaft 8. These ofcourse will be suitably located and will mesh with each other in auysuitable manner.

For the crank mechanism shown in Fig. 6 may be substituted such a one as shown in Figa-7, which may consist of bending the rods 17 and 18. 'lhesepbent rods may be connected to a crank-arm 43 in this case, which surrounds the shaft 8, as seen in Fig. 7. This IIO arrangement does not necessitate displacing the shaft S-for instance, as seen in Fig. 6-y butnevertheless permits the knuckle-pivot point to pass beyond the aforesaid line of centers.

It will be seen that primarily this invention may consist of a single shaft operable from a single point and through the instrumentality of which, together with suit-able trains of mechanism, a plurality of doors on each of the car sides for a plurality of openings of dumping-cars may be simultaneously and efficiently effected; that in combination with a single shaft and means employed the parts may be so related that when the doors are closed there will be an automatic lock, thus preventing the accidental operation of the parts or the opening of the doors.

Such constructions as have been shown in the drawings accompanying this specification are for purposes of illustration, and the special and precise arrangement of parts or precise elements as therein disclosed form only one embodiment of this invention, and the right is reserved to modify the construction, to substitute or omit parts, and to apply the principle of the invention to various types of cars in any manner at will which may most elfectually carry out the ends of practicability.
